A growth model of the cockle (Cerastoderma edule L.) tested in the Oosterschelde estuary (The Netherlands)
We present an ecophysiological model of the bivalve Cerastoderma edule that simulates individual growth and reproduction under ambient conditions in temperature and food availability in the Oosterschelde estuary, SW Netherlands. The model contains feedback loops in the uptake and metabolism of food and in the partitioning of carbon to the internal state variables: somatic tissue, storage, organ...
متن کاملCell-free transmission of a haemic neoplasm in the cockle Cerastoderma edule.
A haemic neoplasm occurs in populations of the common cockle Cerastoderma edule L. along the coast of Ireland. The morphology, epizootiology and distribution of the disease have previously been described. The aetiology of the neoplasm is unknown. In this study transmission of the neoplasm between cockles was accomplished using both whole neoplastic cells and neoplastic cell-free homogenates whi...
متن کاملThe cockle Cerastoderma edule at Northeast Atlantic shores: genetic signatures of glacial refugia
The cockle Cerastoderma (Cardium) edule (L.) ranges from NW Africa to northern Scandinavia. Abundance in shallow coastal sediment is often high, and it attracts commercial harvest. In this study, a complex genetic pattern has been revealed by mitochondrial DNA in 383 individuals from 19 sampling sites. Parsimony network analysis of 79 haplotypes identified two dominant central haplotypes separa...
متن کاملEmergence pattern and spatial distribution of the common cockle Cerastoderma edule
When groups of freshly collected cockles Cerastodema edule L. were transferred to laboratory conditions and exposed to cycles of tldal emersion and immersion and a light regune of 12 h light. l 2 h dark, up to 40% of the group emerged onto the surface of the substratum during emersion at the onset of darkness. This pattern of emergence decreased in intensity from 37% to 10% of all individuals e...
متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
